[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown in the figure, the present invention provides a lime kiln discharge cooling device, including a closed box 1. Cooling components 3 are provided on both sides of the closed box 1 and extend into the interior of the closed box 1. The cooling components 3 are used at least for cooling the lime discharged from the lime kiln. The cooling components 3 include condensation boxes 31 and collection boxes 32 located on both sides of the closed box 1. A water inlet pipe 33 is installed above the condensation box 31. Several heat exchange pipes 34 inserted into the interior of the closed box 1 are provided on the upper part of the water inlet pipe 33. A return pipe 35 located on the other side of the closed box 1 is connected to the several heat exchange pipes 34. Several one-way valves 36 are installed on the return pipe 35. Several rotary conveying components 9 are provided inside the closed box 1.

[0027] In this embodiment, a closed box 1 is included. The closed box 1 is a sealed structure that enables dust-free conveying of lime products after discharge. Cooling components 3 are provided on both sides of the closed box 1, extending into the interior of the closed box 1. The cooling components 3 are used at least for cooling the lime discharged from the lime kiln, ensuring the room temperature environment of the factory and facilitating subsequent production operations of lime products.

[0028] Specifically, the cooling assembly 3 includes a condenser 31 and a collection box 32 located on both sides of the enclosed box 1. The condenser 31 is equipped with a condenser to cool the liquid inside the condenser 31, making it a cryogenic liquid. A water inlet pipe 33 is installed above the condenser 31. Several heat exchange tubes 34 inserted into the enclosed box 1 are installed on the upper part of the water inlet pipe 33. A water pump is installed inside the condenser 31. The cryogenic liquid can be transported to the heat exchange tubes 34 through the water pump and the water inlet pipe 33. The heat exchange tubes 34 inserted into the enclosed box 1 are used to cool the inside of the enclosed box 1, so that the lime is cooled during transportation. A return pipe 35 located on the other side of the enclosed box 1 is connected to several heat exchange tubes 34. The liquid inside the heat exchange tubes 34 is collected through the return pipe 35. Several one-way valves 36 are installed on the return pipe 35. The one-way valves ensure that the cryogenic liquid can enter the heat exchange tubes 34 better and avoid backflow.

[0029] Specifically, the collection box 32 and the condensation box 31 are connected by a pipeline and a water pump. The water pump pumps the high-temperature liquid inside the collection box 32 to the condensation box 31 through the pipeline, thereby forming a liquid circulation and achieving a continuous cooling effect inside the closed box 1.

[0030] In this embodiment, the interior of the enclosed box 1 is provided with several rotary conveying components 9, which can convey lime products inside the enclosed box 1.

[0031] Specifically, the conveying assembly 9 includes a saddle 91, a connecting arm 92 fixedly installed on one side of the saddle 91, and a conveying hopper 93 installed at the end of the connecting arm 92. The inside of the conveying hopper 93 is used to store lime. Under the drive of the drive device 7, several conveying hoppers 93 rotate continuously to achieve the lifting and conveying of lime products.

[0032] Specifically, the side wall of the hopper 93 is provided with several through holes 94;

[0033] Specifically, the through hole 94 is an upwardly inclined angled hole design with an upward inclination angle of at least 45 degrees. This inclined hole design not only enables the conveying of lime without causing the lime inside the conveying hopper 93 to fall out, but also facilitates the dissipation of heat from the lime inside the conveying hopper 93 through the through hole 94. The heat then enters the interior of the enclosed box 1, where the cooling component 3 is used to cool the interior of the enclosed box 1.

[0034] In this embodiment, a drive device 7 is provided inside the enclosed box 1. The drive device 7 includes a drive wheel 71, a driven wheel 72 and a transmission chain 8. The motor that starts the drive wheel 71 can work with the driven wheel 72 to drive the transmission chain 8 to rotate. The transmission chain 8 drives the conveying hopper 93 to rotate.

[0035] In this embodiment, a support base 2 is fixedly installed at the bottom of the enclosed box 1. The bottom of the support base 2 is a planar structure, which is conducive to the stable support of the enclosed box 1.

[0036] In this embodiment, a feed hopper 5 is provided on the lower side of one side of the enclosed box 1, and a discharge hopper 6 is provided on the top side of the enclosed box 1. The lime from the kiln enters the feed hopper 5, is conveyed and lifted by the conveying hopper 93, and is discharged to a processing position by the discharge hopper 6.

[0037] In this embodiment, a dust removal module 4 is provided on the top side of the enclosed box 1. The dust removal module 4 consists of a fan and a dust removal bag. The dust removal module 4 collects the dust inside the enclosed box 1. When the fan is turned on, the dust and air can be absorbed, and the dust can be filtered through the dust removal bag.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
